Please help...

I just downloaded Limewire...and I'm having a problem with viewing Monitor. I go to click on "Enable" and I get an error message. "Your client is a Leaf Node Shielded by an Ultrapeer~Hence you will see few or no searches in the monitor window"

Ok, what is all that? And what can I do to be able to view the Monitor? Please help, I'm new to this "Limewire"

Thanks,
Beija
